After a bit of advice please, I have a 2005 Ducato based campervan and the coolant level light is on and the coolant bottle is at its correct level. The temperature when travelling is fine so I’m guessing it’s a sensor fault. My question is, where is it located and is it a job that can be done by myself? Thanks in advance for any help.

Did you get anywhere with this? I ask as like you I have a ducato based motorhome and it looks like I have the same issue :-(
